Surface Temperature of the Sun - The amount of radiant power produced by the sun is approximately 3.9 x 10^26 watts. Assume the sun is a perfect blackbody sphere with a radius of 6.96 x 10^8 meters, find its surface temperature (in K ...
Atmospheric Physics - The surface of the sun has a temperature of about 6.0 x 10^3K. This hot gas contains hydrogen atoms (m = 1.67 x 10^-27) find the rms speed of these atoms.
